I was running a test on LoadRunner vugen when I got the error:
"Message id [-13992] was not saved - Auto log cache is too small to
contain the message"
The script fails at the block of code written here below:
int m, i;
lr_save_string("","a_buf")
m = atoi(lr_eval_string("{dcDownloads_count}"))
for(i=0;i<=m;i++)
{
if(i<m)
lr_param_sprintf("a_buf",do something manipulating a_buf)
else
lr_param_sprintf("a_buf", do some other things with a_buf)
lr_param_sprintf(("a_buf", do some other things with a_buf) /*the same above sprintf statement was copied by mistake somehow*/
}
I was able to realise that the same sprintf statement was written twice outside of the if..else block. I just removed it and the script worked fine.
But my question is: why did I get the mentioned error with the above code ?
I thought "a_buf" would be overwritten with the same statement everytime after coming out of the if.. else block and I might have got the error in the output which might have resulted in my web request failing or not downloading the required records.
Why would I get this runtime error? What does it mean?
Thanks
The message means an internal buffer used for saving messages is not large enough.
Solution:
Set AutoLogBufferSize in the log section in your default.cfg file.
Following sample set it to 999 KB
[Log]
AutoLogBufferSize=999

I'm trying to create my own Windows service in C according to this tutorial. My event message definition file looks like this
EventLogMessages.mc:
MessageIdTypedef=DWORD
SeverityNames=(
Success=0x0:STATUS_SEVERITY_SUCCESS
Info=0x1:STATUS_SEVERITY_INFO
Warning=0x2:STATUS_SEVERITY_WARNING
Error=0x3:STATUS_SEVERITY_ERROR
)
FacilityNames=(
System=0x0:FACILITY_SYSTEM
Runtime=0x2:FACILITY_RUNTIME
Stubs=0x3:FACILITY_STUBS
Io=0x4:FACILITY_IO_ERROR_CODE
)
LanguageNames=(English=0x409:MSG00409)
; // The following are message definitions.
MessageId=0x1
Severity=Success
Facility=Runtime
SymbolicName=SVCEVENT_STATUS_REPORT
Language=English
Status report: %2.
.
MessageId=0x2
Severity=Error
Facility=System
SymbolicName=SVCEVENT_INIT_SYSCALL_ERROR
Language=English
Essential syscall failed when starting the service: %2.
.
MessageId=0x3
Severity=Error
Facility=Runtime
SymbolicName=SVCEVENT_CUSTOM_ERROR
Language=English
Service-specific error: %2.
.
; // A message file must end with a period on its own line
; // followed by a blank line.
It's almost a copy of the sample file from docs.
However whenever i compile this file, start the service and open the Event Viewer, i see all messages from my service as "Level: Error", even those that should have lower severity.
The event IDs and the messages are correct, but the severity is always wrong.
I opened the the generated header file EventLogMessages.h and here it seems alright as well.
#define SVCEVENT_STATUS_REPORT ((DWORD)0x00020001L)
The upper 2 bits (that indicate severity) are correctly set to 0 - STATUS_SEVERITY_SUCCESS.
But regardless, the event is always displayed wrong.
Anyone has a clue why it's wrong and how to fix it?
So i figured it out by trial and error.
The severity is in fact only controlled by the 2nd parameter of ReportEvent and the upper bits of the messageID (that comes from the .mc file and goes to the 4th parameter) are totally ignored.
So to send a "warning" event, instead of defining the message properties like
MessageId=0x2
Severity=Warning
Facility=Runtime
SymbolicName=SVCEVENT_WARNING
...
you need to call the function this way
ReportEvent( hEventSource, EVENTLOG_WARNING_TYPE, 0, SVCEVENT_WARNING, ... );
Not sure what message severity is good for then, but it works.
I'm implementing Offline Playback with HLS Fairplay following the demo in the FairPlay Streaming Server SDK v4.0.1 that uses AVContentSessionKey.
I download three contents, each content is downloaded and persisted correctly, both the .movpkg and its content key on the documents directory, when I turn off the WIFI these three contents downloaded plays correctly without any problems, before playing Im using this code:
let urlAsset = element.urlAsset!
ContentKeyManager.shared.contentKeySession.addContentKeyRecipient(urlAsset)
if !urlAsset.resourceLoader.preloadsEligibleContentKeys {
urlAsset.resourceLoader.preloadsEligibleContentKeys = true
}
self.present(playerViewController, animated: true, completion: {
AssetPlaybackManager.sharedManager.setAssetForPlayback(urlAsset)
})
So far so good. But the problem is when I close the application (Home button to close applications) and then play the downloaded contents, only the last content downloaded plays correctly, the other ones (first and second) send these error on the console.
Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed"

I double check the .movpkg with the keys in the documents directory and appears correctly
/Documents/.keys/one-key
/Documents/.keys/two-key
/Documents/.keys/three-key
Before the error occurs the ContentKeyDelegate is called and the key is loaded and passed to the request correctly.
if persistableContentKeyExistsOnDisk(withContentKeyIdentifier: assetIDString) {
let urlToPersistableKey = urlForPersistableContentKey(withContentKeyIdentifier: assetIDString)
guard let contentKey = FileManager.default.contents(atPath: urlToPersistableKey.path) else {
/
pendingPersistableContentKeyIdentifiers.remove(assetIDString)
return
}

*/
let keyResponse = AVContentKeyResponse(fairPlayStreamingKeyResponseData: contentKey)
/
keyRequest.processContentKeyResponse(keyResponse)
return
}
If I print the contentKeyRecipients the three contents appears correctly

My tests are in iOS 11.1.2 and iOS 11.2 beta 2
I'm not sure what is happening, but seems to be a problem with the persisted key, I don't how if each content needs to be associated with one AVContentKeySession at time.
If someone faced a similar problem, any help would be appreciated.
Thanks in advance
I'm having similar issue.
however, since I need to support iOS 10, I'm not using the new AVContentKeyResponse class. Instead, I'm loading the persistent content key myself, and pass it to the loading request.
Anyway, I'm getting exact the same error as you and same behavior. One thing to note is that if I remove the code that loads persistent content key from disk, and always fetch the key from server, then everything works. But this defeats the purpose of "offline" playback...
So it seems like the system thinks the persistent content key is invalid...
Which TLLV you used on the server side to specify Rental Duration of the downloaded content? Did you use Content key duration TLLV or Offline Key TLLV? If you used Offline Key TLLV you need to double check that "Content ID" field is different for every downloaded movie.
We had encounter this error message, too.
It will happen when content exceed over expiration date which set in server side.
For example :
We give 10 minutes of expiration date for Video A
Download this Video A, and verify CKC delivery correctly (print log)
Play Video A without connection
Take a break (after 11 minutes), close App, and launch App again, select Video A to Play
Show below error message from AVPlayerItem.error.description:
Error Domain=AVFoundationErrorDomain Code=-11800

NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x1d4257310

You can refresh encrypted data again by
AVAssetResourceLoaderDelegate
or use AVContentSessionKey

Make sure you set correct offline content identifier on a serverside. The identifier you set should be associated with the specific rendition/stream allowed by the license. This helped me.
Good Afternoon All,
I am working on an issue in PHPExcel. Using the following code:
try {
$inputFileType = PHPExcel_IOFactory::identify($fileLocation);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load($fileLocation);
} catch(Exception $e) {
die('ERROR LOADING FILE: "'.print_r(pathinfo($fileLocation),true).'": '.$e->getMessage());
} # end try catch
This responses with a this error message:
ERROR LOADING FILE: "Array ( [dirname] => upload [basename] => d10f8...188 [filename] => d10f8....188 ) ": Cell coordinate must be a range of cells.
Which makes no sense since I am not reading the file yet, only loading it. This code has been in place and working without issue for months (Probably 100+ uses), only one file is causing this error. The file is a Office2007 XLSX (Just like all the others), I have converted the file to multiple other formats (xls, xlt, xlsm) but none of copies will load either. I have found nothing of interest in the file that could explain this behavior.
I have not found anything in my logs and am at a loss to understand the error message of 'Cell coordinate must be a range of cells'. I have isolated the code and made sure that this error message is being generated during this try/catch and is not coming from somewhere else.
Any help would be greatly appreciated,
Paul
This error was caused by a print area being defined in one of sheets. I removed all print areas using these instructions (https://support.office.com/en-us/article/Change-or-clear-a-print-area-on-a-worksheet-deed3c1f-d2ca-4b78-b28d-9c17f0b5de34#bmclearprintarea) and then reran the upload and everything worked. Thanks to MarkBaker for his assistance.

I'm building an SPA in AngularJS served by a Laravel (5.1) backend. Of late I've been encountering an annoying error, a server 500 or code 0 error which is abit hard to explain how it comes but let me try to may be someone will understand the dental formula of my problem.
When i start my AngularJS controller, I make several server calls (via independent $http calls from services) to retrieve information i might later need in the controller. For example,
Functions.getGrades()
.then(function(response)
{
$scope.grades = response.data;
});
Subjects.offered()
.then(function(response)
{
$scope.subjects = response.data;
});
Later on i pass these variables (grades or subjects) to a service where they are used for processing. However, these functions are randomly returning code 500 server errors after they run, and sometimes returning status code 0 after running. This happens in a random way and it is hard for me to point out the circumstances leading to their popping up. This leaves me with frequent empty Laravel-ised error screens like the ones shown below.
Anyone reading my mind?
Ok, after a suggestion given in a comment above that I check my Laravel log files (located in storage/logs/laravel.log- Laravel 5.1), i found out that the main error most of these times was this one: 'PDOException' with message 'SQLSTATE[HY000] [1044] Access denied for user ''#'localhost' to database 'forge'' in ..., plus another one that paraphrased something like No valid encrypter found. These were the key opener.
On reading another SO thread here, it said in part:
I solved, sometimes laravel not read APP_KEY in .ENV. And returns a value "SomeRandomString" (default is defined in config / app.php), and have the error "key length is invalid", so the solution is to copy the value of APP_KEY, to the value 'key 'in config / app.php, that's all! I solved!
That was exactly the issue! When loading the DB params from the .env to config/database.php, Laravel was sometimes unable to read the environment variables and went for the fallback default fallback options (forge for DB name and username and SomeRandomString for the APP_KEY). So, to solve this i just did as advised: copied the APP_KEY in .env to the config/app.php and edited the default DB parameters to the actual DB name and username/password I'm using. Just that and i was free from pollution. Hope someone finds this helpful.
Stack community.
I'm using the eval() function in PHP so my users can execute his own code in my website (Yes, i know it is a dangerous function, but that's not the point).
I want to store all the PHP errors that occur during the interpretation of the code, is there a way to fetch all of them? i want to get and register them in a table of my database.
The error_get_last gets only the last error, but i want all of them.
Help me, please. It is even possible?
General
You cannot use eval() for this, as the evaled code will run in the current context, meaning that the evaled code can overwrite all vars in your context. Beside from security considerations this could / would break functionality. Check this imaginal example:
$mode = 'execute'
// here comes a common code example, it will overwrite `$mode`
eval('
$mode = 'test';
if(....) { ...
');
// here comes your code again, will fail
switch ( $mode) {
...
}
Error Tracking
You cannot track the errors this way. One method would be to use set_error_handler() to register a custom error handler which stores the errors to db. This would work, but what if the user uses the function in it's code? Check the following examples:
set_error_handler('my_handler');
function my_handler($errno, $errstr, $errfile, $errline) {
db_save($errstr, ...);
}
eval('
$a = 1 / 0; // will trigger a warning
echo $b; // variable not defined
'
);
This would work. But problems will arise if have an evaled code like this:
eval('
restore_error_handler();
$a = 1 / 0; // will trigger a warning
echo $b; // variable not defined
'
);
Solution
A common solution to make it possible that others can execute code on your servers is:
store user code into temporary file
disable critical functions like fopen() ... in the php.ini
execute the temporary php file by php-cli and display output (and errors) to the user
if you separate stdin from stdout when calling the php-cli, you can parse the error messages and store them in a DB
According to the documentation, you just can't :
If there is a parse error in the evaluated code, eval() returns FALSE and execution of the following code continues normally. It is not possible to catch a parse error in eval() using set_error_handler().
EDIT: you can't do it with eval(), but you apparently can with php_check_syntax function. You have to write the code to a file in order to check its syntax.
